Machinists, toolmakers, and engineers, this pin gauge set is a precision measuring essential. You get 101 individual steel pins, each with a laser-marked diameter, covering a range from 2.00 mm up to 3.00 mm in super fine increments of 0.01 mm. That means you have a pin for 2.00, 2.01, 2.02... all the way to 3.00 mm. They're used as 'go/no-go' gauges: you try to insert a pin into a hole you've drilled or machined. If the 2.50 mm pin fits but the 2.51 mm pin doesn't, you know your hole is exactly 2.50 mm (within a tiny tolerance of +/-0.001mm). They're perfect for checking hole sizes, slot widths, distances between holes, and even for calibrating micrometers. Each pin is 50mm long and comes in its own marked slot in a sturdy plastic storage case, which keeps them organized, prevents rust, and makes them portable. An indispensable tool for quality control and precision work in any workshop.
